Hi Mark Thanks for your input. As you say when using the BC/IB5 box (as I plan to) the problem area is the crank pulley end. The blacktop water pump runs in opposite direction to silvertop (anti clockwise instead of clockwise) so a simple triangular belt drive config (crank water pump alternator) spins the pump the wrong way. Most of the kit car builders solve this by fitting one of the extra idler pulley kits which drives the water pump off the back of the belt - but this solution obviously uses the original type wide flat ribbed belt so engine width stays the same. Reverse impellers/pumps are available for blacktop i.e. the pump rotation direction is same as original but it pumps opposite way.- these are not cheap but still less expensive than going the electric pump route. So currently it seems he best way to go would be a simple triangle belt config using a reverse impeller water pump and low front mounted alternator (as per XR2) - all using V belt pulleys. Decent engine mounts and a top stabiliser bar to bulkhead would hopefully keep it all in place. John
